Objective: The aim of this study was to investigate sex differences in suicide ideation and attempt at different career stages and test hypotheses derived from the Interpersonal Theory of Suicide (IPTS) in a sample of veterinarians.
Method: The sample of currently practicing veterinarians used for this study (N = 10,319) was derived from a larger sample. Participants completed an online self-report questionnaire.
Results: As predicted, women generally had a higher prevalence of suicide ideation and attempt across career stages, except men and women showed similar rates of suicide attempt after veterinary school. Contrary to hypotheses, no interaction effects between IPTS variables were observed. However, perceived burdensomeness, thwarted belongingness, and hopelessness exhibited the main effects of suicide ideation, and there were main effects of perceived burdensomeness and hopelessness on suicide attempt. Compared with perceived burdensomeness and thwarted belongingness, hopelessness had a relatively more robust relationship with suicide ideation. We also found a significant relationship between fearlessness about death and suicide attempt, but no relationship between self-reported pain tolerance and suicide attempt.
Conclusions: Some of our findings were consistent with the IPTS while others were not. Future research would benefit from a longitudinal examination of suicidality in veterinarians.
